Teaching Workload and Scientific Productivity: Insights from Mexico

What is this article about?

This article explains the impact of teaching workload on scientific productivity in a private Mexican university. Based on data from 785 professors, the study by Ramirez-Montoya et al. analyzes how factors like teaching hours, researcher accreditation (SNI), age, and thesis supervision influence Scopus-indexed publications.

Why is this important?

According to the research, in Latin America, many full-time professors are heavily involved in teaching. Understanding the real factors that affect their research output can inform policy decisions and institutional strategies for enhancing academic productivity.

Key Findings: What really affects scientific output?

1. Teaching hours do not reduce research productivity

Contrary to the initial hypothesis, the number of groups taught per year did not significantly impact the number of scientific articles published.

2. SNI level is the top predictor of productivity

The Sistema Nacional de Investigadores (SNI) accreditation level had the strongest positive correlation with research output. For instance, SNI Level 3 professors published up to 7.3 papers annually, on average.

3. Research contracts outperform teaching contracts

Professors with exclusive research contracts had significantly higher publication rates than those with administrative or teaching-only roles.

4. Thesis supervision boosts publication rates

The number of advised undergraduate and graduate theses was positively linked to scientific productivity, indicating that mentoring students contributes to research generation.

Disciplinary Differences: Where is productivity highest?

• Engineering and Sciences (EIC) and Medicine (EMCS) had the highest publication rates.

• These fields also showed higher co-authorship averages, which may facilitate more frequent publishing.

• Professors in Humanities and Arts had lower outputs, reflecting structural differences in publishing norms.

Teaching Level Matters: Who is more productive?

This article explains that professors who taught only at the undergraduate level had significantly lower scientific output. In contrast, those involved in graduate teaching or with mixed roles were more likely to publish.

FAQs

Q: Does teaching more classes reduce research output?
A: No. The study found no significant correlation between number of courses taught and number of publications.

Q: What increases research productivity the most?
A: Higher SNI level, exclusive research contracts, and thesis supervision.

Q: Are all disciplines equally productive?
A: No. Engineering and Medicine outperform other fields in publication volume and co-authorship.

Q: Does teaching undergraduates affect research negatively?
A: Yes. Teaching exclusively at the undergraduate level is associated with lower research output.
